About

The objective of this study is to investigate the cardiopulmonary health effects of indoor air purification and different indoor environmental factors among school students in Beijing.

Full description

This randomized, double-blind crossover study was conducted to explore the cardiopulmonary effects of ionization air purification among 48 children in Beijing. Real or sham purification was performed in classrooms for 5 weekdays in a random order with a 2-month wash-out period. During the study periods, different indoor environmental factors were monitored including size-fractionated particulate matter (PM), black carbon (BC), ozone, carbon dioxide (CO2), negative air ions (NAI), noise, temperature and relative humidity, which were controlled as confounders in the analysis of the effects of indoor air purification. In addition, we analyzed the cardiopulmonary effects of those environmental factors on the children.
